Look at stock BMW tire sizes and specific models on tire rack. look at that tire, go to "specs" and write down the revs/mile for the OE tires...THIS should give you an idea of the design target. Basically the BMW sizes are under half a percent difference
Where did you get 3%?

Thanks ard.
Although the staggered looks cool and aggressive, I decided against it. Didn't want to deal with the differential issues. Also the headaches with not being able to rotate so you have to replace tires more often.
